Some can. But the big mega power ones here run FSK or in reality MSK about
25-50Hz from what I can tell. The other comment I have is that there no
published data on the stability or reference. I could speculate its good
but have no idea actually.
Would have to build a receiver to figure it out.
Regards
Paul.
